BUTTON.

$PEGIFICA'I'ION forming part of Letters Patent No. 661,337, datedNovember 6, 1900. Application filed June 21, 1899. $erial N6. 721,379-(No model.)

To all whom it may concern.-

Be it known that I, EDWIN GEBHARDT, a citizen of the United States,residing in Cincinati, county of Hamilton, and State of Ohio, haveinvented certain new and useful Improvements in Buttons, of which thefollowing is a full, clear, and exact description, reference being hadto the accompanying drawings, forming part of this specification.

My invention relates to improvements in buttons intended for lapels ofcoats and the like, and has particular relation to a certain novel anduseful method, to be hereinafter particularly pointed out and claimed,of securing the back of the button, whereby the buttonhole will belocked from opening and the button firmly fastened to the garmentwithout any danger of displacement or loss.

The invention consists, essentially, of a rotating plate carrying prongsto be embedded in the cloth of the garment to hold the button in place,which plate is permanently secured to the button-back, but so as torotate freely thereon. The button-back is screwthreaded to screw on thethreaded shank of the button, and as this is done the prongs of theplate catch in the cloth and the plate remains fixed while the back isrotated, forcing the prongs into the cloth and securely fastening thebutton.

In the drawings, Figure 1 is a perspective view of my improved button.Fig. 2 is a front view of the button-back. Fig. 3 is a central sectionof myimproved button, taken through the coat-lapel.

A is the head of the button, of course of any desired shape or designfor a pin, badge, or the like. This head is provided with a shank B,which is screw-threaded, as shown.

C is the button-back, which is provided with a central screw-threadedopening to fasten on the shank of the button.

D is a plate carrying a series of prongs or teeth a a, which arepreferably beveled or inclined to catch more readily in the cloth. Thisplate D is permanently secured to the button-back in any convenient Way.In one of these, and possibly the preferable way, as the cheapest andsimplest, theplateis mounted so as to turn or rotate freely on the hublike portion Z; of the back, and then the outer edges of the hub portionare upset to hold the plate in place. Other methods of holding the plateto the button-back can of course be readily devised, so as to allow theplate to m tate freely on the back while being held permanently thereon.

Tofasten the button, the shank is passed through the buttonhole, and theback is then screwed onto the shank. As the back is turned the teeth ofthe plate will catch in and be driven into the cloth. This will holdshut the buttonhole and fasten the button securely to the lapel of thegarment.

Buttons provided with my improvements are intended more particularly forlapel-buttons, in which there is an emblem or some fancy design mountedon the head of the button and in which it is essential that the headshould remain in one position. It is also desirable that the prongs thathold the button to the garment should not pierce the garment from thefront. In order therefore to provide prongs for holding the button inand to enable the button-back to be screwed up tightly, it is essentialthat the prong-carrying plate should rotate if the head is to remain inone fixed position. Otherwise as soon as the prongs catch in the cloththey would tear the cloth. For this reason the rotating plate carryingthe prongs forms the principal feature of my invention.

Having thus described my invention, what I claim, and desire to secureby Letters Patent, is-

1. In a button, a screw-threaded shank, and a separable button-back tobe screwed thereon, with a plate carrying teeth or prongs and means forsecuring said plate loosely to the back so as to rotate freely withreference thereto,substantially as shown and described.

2. In a button, ascrew-threaded shank, and a separable back providedwith a hub portion and a plate carrying prongs mounted on said hub torotate freely thereon, said hub be ing upset or riveted to hold saidplate to the back, substantially as shown and described.
